So I ran into madmaxx on another board and was helping answer some questions for him. So as a sign of good will I have decided to post the info he wante here so we have something productive (ain't I just a nice guy)
ok so here are some pics of my now dormant 1974 h1/ fzr bike. These are the only pics I have and the bike is in the back of pop's garage and not easy to get to:

Ok, this is probably the slowest project I have ever worked on. I have been building this bike since 2002 and haven't worked on it yet in 2007. That being said here is all the info I can muster:
Rear end:
The rear is a stock 1988-89 fzr400 swingarm I found in a junkyard. The pivot bolt is the same size as the h1 as is the swingarm width. I removed a set of washers from the end caps and the swinger bolted in with the stock h1 mount. For the shocks I took the arm to a friend of mine who tig welded (the arm is aluminum) the dual shock mounts. In retorspect I should have monoshocked it but I wanted the look of dual shocks. If I were to monoshock it I would have cut the mid brace top shock mount out of an fzr600 and welded it into the h1 frame (the fzr600 subframe is steel). The fzr600s have a very similar swingarm but it is steel which makes adding the dual shock mounts easier if you want to go that way. Howvever you are going to need the fzr400 rear wheel and brake as it is narrower and the chain line is almost spot on for an h1 (it is spot on for an h2 - between 1/4 and 1/8 inch off for an h1). Instead of the 160 rear the fzr400 runs you want a 150 and either deck the sprocket carrier or use an custom motor sprocket to make up the diff (sprocket specalists). I used 2002 r6 rear sets because the rear master is the same and the rearset brackets have the mounts for the master built on to them. Easy as pie. All of this should work for an early h1 and early h2 as well. The fzr400 arm is too short for a later h2 and makes the bike look funny. You will have middle pipe clearance issues with this setup so be prepared to run custom chambers or hack existing aftermarket ones. Stock exhaust is too heavy and valuable to waste time modifying it to work. If you can used wirges pipes are junk and cheap (worse performes than stock pipes) - therefore you can hack them if you are a DIY. If you want to pay someone tomcat on the kawi board will make you a set for around $700 or so (don't quote me on that) and the bike will scream.
Front end:
I did it the hard way. I had a machinist grind and press out the h1 stem and then I put it in the fzr600 lower clamp. I got the whole front end from a wrecking yard for $100 so I didn't mind the expirmentation. The 1994 FZR600 front end has a steel lower clamp so my h1 stem was welded in after it was installed in the clamp. After that I bored the top of the clamp to slip over the larger h1 stem and bolted her on. The end result looks like kawasaki did it from the factory. Since then someone else has figured out how to adapt a gsxr front end using only a spacer for the top (the bottom bearing surface of the fzr600 and the h1 take the same bearings, that is why I chose it - the gsxr front end swap is common on fzrs). Search kawasakitriplesworldwide.com and you'll find the post on it.
Maxx - there is a guy in sweeden with a really trick 1970 h1 with h2 motor and GSXR upsidedown forks and monoshock rear - looks badass. You can e-mail me any time with questions and trouble shooting, I am pretty helpful when it come to this end of things.
hope the air is clear.
